Validation
OK, I am trying to check for blank fields in all of the input tags, also if the tag has the word 'other' in it, I am disregarding the check. THe issue is that it gets to 0 in the for loop and bombs. below:
Code:
var inputFields = document.all.tags("INPUT") //grabs all input tags
for(i=0; i < inputFields.length; i++)
{
if (inputFields[i].value == '')
{
alert("Checking " + inputFields[i].name.substr(3,5));
if(inputFields[i].name.substr(3, 5) != 'other')
{
alert('Please fill out '+ inputFields[i].name);
inputFields[i].name.focus
return false;
break;
}
return true;
}
return true;
}

Take out the two return true statement.
Heres is how u should do it.
Code:
<html>
<head>
<script>
function validate()
{
var inputFields = document.all.tags("INPUT") //grabs all input tags
for(i=0; i < inputFields.length; i++)
{
if (inputFields[i].value == '')
{
alert("Checking " + inputFields[i].name.substr(3,5));
if(inputFields[i].name.substr(3, 5) != 'other')
{
alert('Please fill out '+ inputFields[i].name);
inputFields[i].name.focus
return false;
break;
}
}
}
}
</script>
</head>
<body>
<form name=form1>
<input type=textbox name=i1 size="20">
<br>
<input type=textbox name=i2 size="20">
<br>
<input type=textbox name=i3 size="20">
<br>
<input type=button value=submit onclick="JavaScript:validate()">
</form>
</body>
</html>
Hope this helps

There is a great war coming. Are you sure you are on the right side? Atleast I have chosen a side.

Thanks, I appreciate that. When return true is in there, it is just returning a boolean value of true?

yes it is, and thats why the full loop was not being processed and it was acting as break statement.

If you're willing to give up IE4 support in favor of Gecko support you should change the script:
Code:
function validate()
{
var inputFields = document.getElementsByTagName("INPUT") //grabs all input tags
for(i=0; i < inputFields.length; i++)
{
if (inputFields[i].value == '')
{
alert("Checking " + inputFields[i].name.substr(3,5));
if(inputFields[i].name.substr(3, 5) != 'other')
{
alert('Please fill out '+ inputFields[i].name);
inputFields[i].focus();
return false;
break;
}
}
}
}
It's not as if
inputFields[i].name.focus
had any effect anyway.
